    unparse-args

    Build Status

    A Node module to help you unparse parsed arguments back to the original argv array or a command string.

    This module will:

    • unparse parsed arguments back to an argv array
    • easily regenerate a command string based on the unparsed array
    • work with yargs, minimist, and subarg (also handles subcontexts)

    Use Scenario

    Imagine a hypothetical command string with flags, subcommands, options... etc:

    node example.js another --number 297261 -t something -x 'something longer than just 1 word' -a -e

    Popular argument parsing modules for Node: yargs, subarg, and minimist all parse these into an object like:

    var args = { 
        _: [ 'node', '/Users/arjun/example/example.js', 'another' ],
        number: 297261,
        t: 'something',
        x: 'something longer than just 1 word',
        a: true,
        e: true
    };

    But we might want to manipulate it and flatten it out again to be like:

    ['node', '/Users/arjun/example/example.js', 'another', '--number', '297261', '-t', 'something', '-x', 'something longer than just 1 word', '-a', '-e']

    Installation

    npm install --save unparse-args

    Basic Usage

    Include

    var unparse = require('unparse-args');

    Assume some parsed arguments.

    var parsed = subarg(process.argv);
    // OR
    var parsed = minimist(process.argv);
    // OR
    var parsed = yargs.parse(process.argv);

    Unparse Parsed Arguments

    Easily unparse them into an array.

    var unparsed = unparse(parsed)
    console.log(unparsed); // ['node', 'example.js', 'another', '--number', '297261', '-t', 'something', '-x', 'something longer than just 1 word', '-a', '-e']

    Convert Arg Array to Command String

    var command_string = unparsed.command_string;
    console.log(command_string); // node example.js another --number 297261 -t something -x 'something longer than just 1 word' -a -e

    I know I know, unparsed is an array, so how can it have a property?? Magic.
